Quartermile

CW-FS Firestop | AB10 Acoustic Barrier Overlay | CVB/C10 Acoustic Void Barrier | MI Mullion Insert 

Masterplanned by architects Foster + Partners, Quartermile is one of the largest and most comprehensive regeneration schemes in Scotland, combining new build with selective refurbishment. 

The development provides over 1,000 apartments along with 370,000ft² of Grade A office accommodation, 65,000ft² of retail and leisure space and seven acres of open landscaping. 

Siderise was approached by Edinburgh based façade specialists, Charles Henshaw & Sons, to find a bespoke solution that would meet the acoustic performance criteria requirements for Quartermile’s Q20 – Q25 apartment buildings, all of which feature curtain walling. 

The principal challenge was to achieve an on-site test value in excess of the 53dB DnT,w requirement for Building Regulations in Scotland. The target was 56dB DnT,w. For Henshaw this meant that the façade system— a potential weak point for flanking sound transmission— needed to achieve between 61-66dB Dnf,w flanking via the façade, past the floor slab areas, to exceed Building Regulations. 

Commenting on the collaborative working relationship with Siderise, Donald Fraser the Design Director at Henshaw, said:

“We had very informative and lengthy discussions with Mike Carrick of Siderise who helped us in achieving a far better detail at the slab edge, which not only met with the approval of RMP, it also proved to be the optimum solution.” 

CW-FS Firestop was used along with AB10 Acoustic Barrier Overlay and CVB/C10 Acoustic Void Barrier to improve floor-to-floor acoustic performance and form a simple, high performance sound barrier. The acoustic matt was held up with 40mm x 20mm x 1.6mm galvanised angles to stop it sinking. MI Mullion Inserts were also specified to further increase the acoustic performance at the critical mullion detail.
